Not exactly. The Independence, Lil Snoozy
, and the larger Oliver
Elite II are the only traditional side-by-side twin offerings.
Several small rear-entry units- Hunter Compact Jr., Trailswest Campster
, Little Joe- work as twins, but they aren't self-contained.
Liberty models (16' and 17') can be configured as narrow twins, and some owners have found ways to make them a little wider. They're more common in the used market- been around a lot longer than the Independence.
And of course side dinette models could be considered "twins" if one person slept on the back bed and one on the side bed. You could even reconfigure the back bed into a U-shaped dinette (minus the big table), with a single bunk across the back and you'd still have the wings for seating even when both beds are in use.
With small trailers you sometimes have to think outside the box!
